Sommen automatiseren groep 3-4
Juf Jannie apps
With this app, your child practices answering addition and subtraction problems quickly and smoothly. Automatization is the foundation for all subsequent arithmetic steps — from fractions to larger problems.
For whom:
Children in Group 3 and Group 4 who want to automate addition and subtraction problems up to 10 or up to 20.
What your child learns:
• Addition problems up to 10.
• Addition problems up to 20.
• Subtraction problems up to 10.
• Subtraction problems up to 20.
The exercises:
• Doubling (1+1, 2+2, etc.).
• Adding or subtracting one (3+1, 4-1).
• Number bonds of 10 (which numbers add up to ten?).
• Mixed sums.
• Choose the sum that matches the answer (three sums, three answers).
• Test with overview. What makes the app special:
• Choose sums up to 10 or up to 20.
• Choose addition sums, subtraction sums, or both.
• Practice the intermediate steps first (doubling, adding/subtracting one, number splitting).
• Aligns with math instruction in the classroom.
• Test your child and see which sums still need practice.
Why parents choose Juf Jannie:
• One-time purchase — no subscription, no ads.
• Works offline, on tablet and phone.

• Created by a former teacher, aligns with primary school curriculum.
About Juf Jannie
Juf Jannie creates educational apps for children that align with primary school subject matter. The exercises are the same as those children receive at school, but your child practices through play and immediately hears what is going well and what could be improved. Learning through play is central. Also check out our other apps by Juf Jannie for toddlers, preschoolers, and groups 1 through 6 in the Play Store.
